Such as using caribbeaners to indicate you're wlw, is there a form if that for mlm?

I know its common to use caribbeaners on jeans/belts to "tell" people you are wlw, but as a mlm, is there any of that for gay people? I THINK theres like, a white bandana to show it, even just to show your LGBTQ, besides the obvious pins and such.
